This is the set-up: a document belongs to a category. Category is a class with
an ID (Integer - auto generated), a name and a description. One category can
have many documents.
A data table of documents is displayed. The category is in a selectOne and the
name is displayed. This is what it looks like in the view:
| <h:selectOneMenu id="category" value="#{document.category.categoryID}"
required="true">
| <f:selectItems value="#{categorySessionBean.categoryList}" />
| </h:selectOneMenu>
|
This is what an f:selecItem looks like:
| categoryList = new SelectItem[categories.size()];
| int i=0;
| for(Category cat:categories){
| categoryList(i)=new SelectItem(cat.getCategoryID(), cat.getName());
| i++;
| }
|
The () after categoryList should be square brackets. It is seen as formatting
and ignored.
I've tried s:selectItems and it doesn't work for me. I get and "invalid value"
when trying to do an update with it. Maybe the place holders have something to
do with it.
How can I use a selectOne to change the category of a document? The display is
right, the xhtml code is right, just it does not work.
Any help will be greatly appreciated.
